Application April 24, 1956, Serial No. 580,350

2 Claims. (Cl. 24011.2)

This invention relates to new and useful improvements in lamp structures, more particularly for use on lamp posts for home lawn lighting, and it is among the objects thereof to provide a novel combination of a glass lighting fixture and shade that is highly ornamental and of simple, durable construction, the lamp being in the main constituted of the glass fixture element.

The invention will become more apparent from a consideration of the accompanying drawing constituting a part hereof in which like reference characters designate like parts, and in which:

Figure 1 is a top plan view of a lighting fixture and shade embodying the principles of this invention with the shade partially cut away; and,

Figure 2, a side elevational view thereof, partially in cross section.

In the drawing, the numeral 1 designates a lamp post such as is used for lawn lighting on which is mounted a lamp bracket 2 secured by a screw 3. Mounted on the bracket 2 is a glass lighting fixture consisting of an integral fluted body portion 4 with a curved dome portion 5 and a reduced knob or end portion 6, all integrally formed as a unit lighting fixture. The base of the fixture is provided with threads '7 of a pitch of 2 /2 threads per inch with three starts around, which threaded portion fits into a complementary threaded portion of the cast cup or bracket 2. The sides of the body portion 4 are fluted and terminate in a bead 8 that rests on a shoulder 9 of the bracket 2. The top of the lighting fixture is provided with a shoulder or neck 10 intermediate the rounded portion 5 and the knob 6 which is provided with threads 11, there being 2 /3 threads per inch with three starts around, the threads being adapted to interact with the threaded portion 12 of sleeve 13 of a lamp shade 14 made of aluminum, glass or other sheet metal or cast materials.

The metal shade 14 may be of various diameters and, as explained is attached to the light fixture by the simple expedient of screwing it onto the thread 11 of shoulder 10 of the light fixture. The combination of light fixture and shade produces a pleasing ornamental effect and has the advantage over conventional composite glass and metal structures in that the light fixture itself is an integral sealed member which encloses the light bulb 15, as shown in dotted lines in Figure 2. Therefore, there is no possibility of the light bulb being broken from moisture in driving rain, as commonly happens Where light fixtures are made of composite pieces.

Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.

I claim:

1. A lighting fixture for lamp post comprising a glass globe having concavo side walls and convex top wall, the concave side walls terminating in a constricted base for mounting on a post bracket and the convex top wall terminating in a shoulder from which an integral ornamental knob extends in an upward direction, the constricted base portion and the top shoulder portion being provided with external threads for engaging the post mounting bracket and a combined reflector and shade respectively, said lighting fixture constituting an integral sealed member which encloses the light bulb.

2. In combination a lamp post, a mounting bracket at the top of the lamp post having a threaded end, a light globe of glass having a base with threads for engaging the threads of the mounting bracket, said light globe being a sealed integral member having threads on a shoulder at the top thereof and a combined reflector and shade having a threaded flange portion for engaging the threads on the top of the light globe.
